What is the the Proper Butane for my lighter?
You can dramatically extend the useable life of your lighter by using the proper fuel. For butane (gas) lighters, the manufacturers will put their gas through varying degrees of refinement that result in fewer or greater levels of impurities. For instance, both Dunhill and S.T. Dupont butane are ultra-refined, resulting in a very high quality gas with very few impurities. The lower the impurities, the less chance of impurity build-up in the lighter’s internal valves, the lower the chance of damage to the workings of the lighter.
